-heit

See also: heit

German

Alternative forms

-keit

Etymology

From Middle High German -heit, from Old High German -heit, from Proto-West Germanic *-haidu, ultimately from Proto-Germanic *haiduz (“personality, character, manner, way”).^[1] Cognate with Dutch -heid, English -hood, Danish -hed.

Pronunciation

IPA^(key): /-haɪ̯t/, [haɪ̯t]
The suffix has secondary stress when it follows an unstressed syllable and often also when it precedes one. When it is entirely unstressed, the /h/ may be unpronounced in common speech.

Suffix

-heit f (genitive -heit, plural -heiten)

Converts an adjective into a noun and usually denotes an abstract quality of the adjectival root. It is often equivalent to the English suffixes -ness, -th, -ity, -dom:
‎schön (“beautiful”) + ‎-heit → ‎Schönheit (“beauty”)

‎neu (“new”) + ‎-heit → ‎Neuheit (“novelty”)
Converts concrete nouns into abstract nouns:
‎Kind (“child”) + ‎-heit → ‎Kindheit (“childhood”)

‎Christ (“Christian”) + ‎-heit → ‎Christenheit (“Christendom”)

Usage notes

While -heit is the normal form of this suffix, it becomes -keit after certain adjectival suffixes. These are -bar, -ig, -isch, -lich, -sam. For example: ‎nützlich (“useful”) + ‎-heit → ‎Nützlichkeit (“utility”).
Adjectives ending in unstressed -el, -er usually take -keit as well: ‎eitel (“vain”) + ‎-heit → ‎Eitelkeit (“vanity”), ‎mager (“meagre”) + ‎-heit → ‎Magerkeit (“meagreness”). However, there are a handful of exceptions, e.g. Dunkelheit (“darkness”), Sicherheit (“safety”).
Sometimes -ig- is added to the adjective and the suffix thus becomes -keit. This is the general rule with adjectives in -haft and -los: ‎fehlerhaft (“faulty”) + ‎-heit → ‎Fehlerhaftigkeit (“faultiness”). There is also a fairly large number of other adjectives that follow this pattern: ‎müde (“tired”) + ‎-heit → ‎Müdigkeit (“tiredness”). Two forms may exist for some adjectives, occasionally with a semantic distinction, e.g. Neuheit (“novelty”) versus Neuigkeit (“news”).
